FEFLOW piCHEM
2D/3D geochemical modelling using PHREEQC in FEFLOW
Geochemical processes have a major influence on groundwater quality, for example in mining, for water supply and in groundwater-dependent ecosystems. Up to now, the simulation of these processes is often limited to batch reactions or transport along one-dimensional flow paths. Adapted software and improved computer hardware allow for much more nowadays!
piChem for FEFLOW has the power to drive this radical change. It supports the convenient extension of any two- or three-dimensional FEFLOW flow and transport model by geochemical reactions. With piChem relying on the PHREEQC reaction simulation engine (developed by the United States Geological Survey) and its standard definitions, the additional effort in model setup and results evaluation becomes manageable.
